4. The final product of the city environment is found in the new types of personality which it engenders. Here the latent energies and capacities of individuals find expression and locate themselves within the range of a favorable milieu. This possibility of segregating one’s self from the crowd develops and accentuates what there is of individuality in the human personality. The city gives an opportunity to men to practice their specialty vocationally and develop it to the utmost degree. It provides also the stimulus and the conditions which tend to bring out those temperamental and psychological qualities within the individual through the multiple behavior patterns which it tolerates.

THE CITY AND THE COUNTRY The city and the country represent two opposite poles in modern civilization. The difference between the two is not merely one of degree, but of kind. Each has its own peculiar type of interests, of social organization, and of humanity. These two worlds are in part antagonistic and in part complementary to each other. The one influences the life of the other, but they are by no means equally matched. The analysis of these differences, antagonisms, and interacting forces has not passed even the descriptive stage.
